Our integrating spheres are available in 5 categories:

Light Measurement Integrating Spheres

EOI’s Light Measurement Integrating Spheres are designed to measure total flux output of various light sources such as tungsten lamps, xenon arc lamps, LEDs, fiber optics and lasers. The ISV210 is a 6 inch sphere with 2 inch diameter ports, while the ISV410 is a 12 inch sphere with 2 or 4 inch ports. The ISV Integrating Spheres utilize closed loop control of the detector/attenuator system to precisely set and maintain the desired output level. A silicon detector continuously monitors the output of the lamps and provides feedback to the attenuator, providing very stable and repeatable performance. Operation of the system is from the controller front panel keypad or via the built in Ethernet and RS-232 computer interfaces (IEEE-488 optional).

Integrating Source Spheres

EOI’s Integrating Source Spheres are designed for the calibration and test of cameras and sensors such as night vision systems, image intensifier cameras, radiometers, UV-vision enhancement systems, focal plane arrays and optical detectors. All of our integrating source spheres utilize closed loop control of the detector/attenuator system to precisely set and maintain the desired output level. A silicon detector continuously monitors the output of the lamps and provides feedback to the attenuator, providing very stable and repeatable performance. Operation of the system is from the controller front panel keypad or via the built in Ethernet and RS-232 computer interfaces. 

Standard Integrating Spheres

EOI also offers individual spheres of various sizes and with different coatings for customers to use at their own discretion. Standard size spheres on offer are 3”, 6”, 8” and 12”. Available coatings are Teflon, Barium Sulfate and Gold. 

Custom Designed Integrating Spheres

EOI’s Modular or Customer Designed Integrating Spheres are designed as required by our customers. We take your requirements and custom engineer a solution using our vast experience. Our engineering expertise can build you a custom solution with varying sphere and port sizes, interior coatings, baffle sizes/styles/locations, targets and stands. 

Sphere Based Systems

EOI’s Sphere Bases Systems set a new performance and capability standard for calibration and testing of sensors and cameras. These systems combine EOI’s expertise in spheres with our expertise in system design, thus enabling the most reliable, repeatable, and quantitative test results.

All integrating spheres are supplied with NIST traceable calibration.
